Technical details
The plugin fails to validate transaction nonces or require authentication before processing option deletion requests, allowing unauthenticated visitors to delete arbitrary WordPress options via manipulated request parameters. The vulnerability stems from missing authorization checks on the option deletion function (CWE-862: Missing Authorization). An attacker can craft requests that delete critical options like admin credentials or plugin activation status without any prior authentication or valid session. This can result in complete lockout of the WordPress admin interface or plugin deactivation across the site. Patches are available in version 6.3.1 and 19.3.
